<p>You can attach a geofence (which can be a polygon or a bounds) to a marker with:</p>
<pre>polygon = map.drawPolygon({
paths: path,
strokeColor: '#BBD8E9',
strokeOpacity: 1,
strokeWeight: 3,
fillColor: '#BBD8E9',
fillOpacity: 0.6
});
map.addMarker({
lat: -12.043333,
lng: -77.028333,
draggable: true,
fences: [polygon],
outside: function(marker, fence){
alert('This marker has been moved outside of its fence');
}
});</pre>
<p>You must define an <strong>outside</strong> callback, which will use this <code>marker</code> and its <code>fence</code>.</p>
<p><span class="label notice">Note: </span>You also can use <code>checkMarkerGeofence</code> or <code>checkGeofence</code> methods.</p>
